Here are some tips on how to type certain characters that differ from regular romaji.
「ん」 = "nn"
Some input methods will be able to figure it out with just one 'n' most of the time but others require you to type it exactly as 'nn'.
Small Characters = prepend 'x' or 'l' (depending on the OS).
For example, 「ぁ」 (smaller than the regular 「あ」) can be typed as "xa" or "la". The input editor will usually type small characters automatically by context such as 「きゃ」 ("kya") or 「ファ」 ("fa"). However, you will sometimes need to type it explicitly for ambiguous situations such as 「ティ」 (typed as "texi" or"teli"). The phonetic representation "ti" will output as 「ち」 instead.
「ぢ」 = "di" and 「づ」 = "du"
Though these characters don't actually have a "d" sound, they belong to the same category as other d-consonant sounds. If you wanted the phonetic "di" （ディ） and "du" （ドゥ） sound, you would need to type "deli/dexi" and "dolu/doxu" as explained above.
